Benefits of technology

Enables efficient and flexible clog removal and pipe inspection by allowing extension of tool length and attachment of specialized tools, reducing waste and resource usage through modular design and quick-release connections.

Problems solved by technology

A drain pipe from a sink, a bathtub, a shower or a toilet often becomes clogged and will not drain properly due to an accumulation of debris, such as hair, toothpaste, solid waste and paper.
The Luoma apparatus may be useful, but its usefulness is limited by its fixed length, its ability to negotiate bends in a drain pipe, its ability to clean hair and other debris from a drain pipe, and it is limited to cleaning hair from a drain pipe and does not provide for serving any other purpose.

embodiment 64

[0069]FIG. 19 shows a side elevation of an embodiment 64 of a drain cleaning apparatus, according to the present invention, in which threaded connections are used to detachably connect a clog-snagging section 66 to a handle element 68. A tool element 70 is connected to an end of the clog-snagging section 66 opposite the end where section 66 is connected to handle element 68. The handle element 68 has an elongate body 68a, which has opposing ends 68b and 68c. A grip 68e is attached to the end 68b to provide a T-shaped handle for convenience in use. Any suitable element can be used as a handle for allowing a user to grip and use the drain cleaning apparatus. A user can grip an end of a clog-snagging member and use the end as a handle. The end 68c is opposite of the gripping end 68b and preferably has a bore 68d, which provides an opening on end 68c. The bore 68d is an elongate cavity having a longitudinal axis coincident with the longitudinal axis of elongate body 68a. The body 68a ma...

Abstract

A drain cleaning apparatus includes a handle and a clog-catching member detachably connected to the handle. Wings, barbs or hooks project radially from the clog-catching member. The wings, barbs or hooks provide an angled projection that catches and holds a clump of debris in a drain pipe for pulling the clump out and unclogging the drain. Different end tools can be removably connected to a clog-catching member or to a smooth extension member to provide multifunctionality. The handle, clog-catching members, smooth extension members and tools can be connected together using a quick-connect connector, such as a snap fastener, a keyhole fastener or a side-release buckle, or a threaded connector. In addition to drain cleaning, the apparatus can be fitted with tools such as a magnet, grabber, light, camera and / or video for retrieval of objects and inspection of a space that is difficult to view directly.
